TRON Lives? At least, in video game form?
The site Gematsu has an article showing that the Brazilian Advisory Rating System has a listing for a game titled TRON: Escape for the PC, PlayStation 4, and Xbox One. There are no other details, other than the game may possibly be released as early as 2015.
I'll update this article if I find out any more details. I speculated on what the game would be like in a previous article, but it's looking as if this game might be somewhat different than expected. There's also a slim chance the game might have been canceled, and its appearance in the Brazilian database is merely a formality. But, I very much doubt that.
The TRON: Escape name, perhaps suggests this could be a reworked version of the Escape from Argon City web game that was made for TRON Uprising?
Thanks to iConiCdays on Reddit for the tip!
